Swansea City announced on Monday that they have appealed against goalkeeper Lukasz Fabianski's dismissal during their 3-1 loss at West Ham United in the Premier League on Sunday.

The former Arsenal goalkeeper was sent off in the 68th minute at Upton Park, with the score at 2-1, for racing out of his area and impeding Diafra Sakho as the West Ham substitute bore down on goal.

But Swansea coach Garry Monk complained afterwards that Sakho had used his arm to nudge the ball past Fabianski and argued that the West Ham forward had not been denied a clear goalscoring opportunity.

"Swansea City can confirm that the club will be appealing the red card issued to goalkeeper Lukasz Fabianski against West Ham on Sunday," Swansea said in a statement.

"The club officially informed the Football Association by today's 1pm (1300 GMT) deadline.

"The Polish international, who faces a one-match ban, was shown a straight red card by referee Chris Foy for impeding Diafra Sakho and denying a clear goalscoring opportunity in the 68th minute of the defeat at the Boleyn Ground.

"The FA will make a decision on the appeal ahead of Sunday's Barclays Premier League clash with Spurs at the Liberty Stadium."
